Explanation of functions (parameters)
2.3.4 Multi-speed operation (Pr. 4
Pr. 24
Used to switch between the predetermined running speeds.
Any speed can be selected by merely switching on/off the corresponding
contact signals (RH, RM, RL, REX signals).
By using these functions with Pr. 1 "maximum frequency" and Pr. 2 "minimum
frequency", up to 17 speeds can be set.
This function is valid in the external operation mode or in the combined
operation mode which is available when Pr. 79 = "3" or "4".

<Setting>
Set the running frequencies in the corresponding parameters.
Each speed (frequency) can be set as desired between 0 and 120Hz during inverter
operation.
When the parameter of any multi-speed setting is read, turn the
setting.
In this case, press the
the external mode.)
The setting is reflected by pressing the
Assign the terminals used for signals RH, RM, RL and REX using Pr. 60 to Pr. 63.
(When terminal assignment is changed using Pr. 60 to Pr. 63, the other functions may
be affected. Please make setting after confirming the function of each terminal.)
